6. Description of content:  Health Canada's Food Directorate completed a premarket safety 
assessment of a food additive submission seeking approval for the use of dimethyl 
dicarbonate (DMDC) as a preservative in fruit wine, cider, and perry (a product of the 
alcoholic fermentation of pear juice).  
DMDC is already permitted for use as a preservativ e in unstandardized water -based non -

Preservatives , effective 27 July 2021.  
The purpose of this communication is to publically announce the Department's decision in
